Halberd exhibitions have long been a platform for groundbreaking outdoor sculptures that captivate audiences with their scale, creativity, and cultural significance. Among the most renowned is *The Guardian*, a towering steel and bronze piece by artist Elena Vázquez, which debuted at the 2015 Halberd Biennale. Its dynamic form, resembling a fusion of weaponry and organic shapes, has made it a landmark in Barcelona’s Parc de la Ciutadella.

Another standout is *Echoes of Time* by Japanese sculptor Hiroshi Nakamura, featured in the 2018 Halberd Open Air Exhibition. This granite and glass installation, reflecting light and shadow, explores themes of memory and permanence. Its location in New York’s High Line Park draws thousands of visitors annually.

The 2020 Halberd Sculpture Symposium introduced *Wings of Unity*, a collaborative work by five international artists. Made from recycled materials, this piece symbolizes global connectivity and environmental awareness. Installed in Berlin’s Tiergarten, it has become a symbol of hope and collaboration.

These sculptures, among others, highlight how halberd exhibitions push the boundaries of public art, blending innovation with cultural dialogue. Their enduring appeal lies in their ability to transform urban landscapes into open-air galleries.
